Hello my name is Dan and I just joined. I have been searching this site and you tube a lot. I almost purchased a tiny $200 coop on eBay, but decided to build myself a coop. I did it for about $200 but I had some supplies laying around. It's 4x10 and should last forever. I didn't paint it yet. It's made of pressure treated wood. I built pvc water and food suppliers. It's caged on all four sides so animals can not get in. Even though it appears an animal can get in from the front i put bricks in place and I am going to put some extra fence going into the ground for added protection. It's not perfect but I think it's good enough. I do plan to let them free range, and hopefully keep them friendly. Tonight I picked up my 3 hens. Very exiting. One is sleeping inside on the perch. One is sleeping inside on the wood shavings, and the other is sleeping out side.
